1 systemd System and Service Manager
5 * Whenever a unit changes state we'll now log this to the
6 journal and show along the unit's own log output in
9 * ConditionPathIsMountPoint= can now properly detect bind
10 mount points too. (Previously, a bind mount of one file
11 system to another place in the file system could not be
12 detected as mount, since they shared struct stat's st_dev
15 * We will now mount the cgroup controllers cpu, cpuacct,
16 cpuset and the controllers net_cls, net_prio together by
19 * nspawn containers will now have a virtualized boot
20 ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted
21 over with a randomized ID at container initialization). This
22 has the effect of making "journalctl -b" do the right thing
25 * The JSON output journal serialization has been updated not
26 to generate "endless" list objects anymore, but rather one
27 JSON object per line. This is more in line how most JSON
28 parsers expect JSON objects. The new output mode
29 "json-pretty" has been added to provide similar output, but
30 neatly aligned for readability by humans.
32 * We dropped all explicit sync() invocations in the shutdown
33 code. The kernel does this implicitly anyway in the kernel
34 reboot() syscall. halt(8)'s -n option is now a compatibility
37 * We now support virtualized reboot() in containers, as
38 supported by newer kernels. We will fall back to exit() if
39 CAP_SYS_REBOOT is not available to the container. Also,
40 nspawn makes use of this now and will actually reboot the
41 container if the containerized OS asks for that.
43 * journalctl will only show local log output by default
44 now. Use --merge (-m) to show remote log output, too.
46 * libsystemd-journal gained the new sd_journal_get_usage()
47 call to determine the current disk usage of all journal
48 files. This is exposed in the new "journalctl --disk-usage"
51 * journald gained a new configuration setting SplitMode= in
52 journald.conf which may be used to control how user journals
53 are split off. See journald.conf(5) for details.
55 * A new condition type ConditionFileNotEmpty= has been added.
57 * tmpfiles' "w" lines now support file globbing, to write
58 multiple files at once.
60 * We added Python bindings for the journal submission
61 APIs. More Python APIs for a number of selected APIs will
62 likely follow. Note that we intend to add native bindings
63 only for the Python language, as we consider it common
64 enough to deserve bindings shipped within systemd. There are
65 various projects outside of systemd that provide bindings
66 for languages such as PHP or Lua.
68 * Many conditions will not resolve specifiers such as %i. They
69 are also available in PathChanged= and related directives of
72 * There's now a new RPM macro definition for the system preset
75 * journald will now warn if it can't foward a message to the
76 syslog daemon because it's socket is full.
78 * timedated will no longer write or process /etc/timezone,
79 except on Debian. As we do not support late mounted /usr
80 anymore /etc/localtime always being a symlink is now safe,
81 and hence the information in /etc/timezone is not necessary
84 * logind will now always resolve one VT for a text getty (VT6
85 by default). Previously if more than 6 X sessions where
86 started they took up all the VTs with auto-spawned gettys,
87 so that no text gettys were available anymore.
89 * udev will now automatically inform the btrfs kernel logic
90 about btrfs RAID components showing up. This should make
91 simple hotplug based btrfs RAID assembly work.
93 * PID 1 will now increase its RLIMIT_NOFILE to 64K by default
94 (but not for its children which will stay at the kernel
95 default). This should allow setups with a lot more listening
98 * systemd will now always pass the configured timezone to the
99 kernel at boot. timedated will do the same when the timezone
102 * logind's inhibition logic has been updated. By default,
103 logind will now handle the lid switch, the power and sleep
104 keys all the time, even in graphical sessions. If DEs want
105 to handle these events on their own they should take the new
106 handle-power-key, handle-sleep-key and handle-lid-switch
107 inhibitors during their runtime. A simple way to achiveve
108 that is to invoke the DE wrapped in an invocation of:
110 systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ...
112 * Access to unit operations is now checked via SELinux taking
113 the unit file label and client process label into account.

125 * Support for reading structured kernel messages from
126 /dev/kmsg has now been added and is enabled by default.
128 * Support for reading kernel messages from /proc/kmsg has now
129 been removed. If you want kernel messages in the journal
130 make sure to run a recent kernel (>= 3.5) that supports
131 reading structured messages from /dev/kmsg (see
132 above). /proc/kmsg is now exclusive property of classic
133 syslog daemons again.
135 * The libudev API gained the new
136 udev_device_new_from_device_id() call.
138 * The logic for file system namespace (ReadOnlyDirectory=,
139 ReadWriteDirectoy=, PrivateTmp=) has been reworked not to
140 require pivot_root() anymore. This means fewer temporary
141 directories are created below /tmp for this feature.
143 * nspawn containers will now see and receive all submounts
144 made on the host OS below the root file system of the
147 * Forward Secure Sealing is now supported for Journal files,
148 which provide cryptographical sealing of journal files so
149 that attackers cannot alter log history anymore without this
150 being detectable. Lennart will soon post a blog story about
151 this explaining it in more detail.
153 * There are two new service settings RestartPreventExitStatus=
154 and SuccessExitStatus= which allow configuration of exit
155 status (exit code or signal) which will be excepted from the
156 restart logic, resp. consider successful.
158 * journalctl gained the new --verify switch that can be used
159 to check the integrity of the structure of journal files and
160 (if Forward Secure Sealing is enabled) the contents of
163 * nspawn containers will now be run with /dev/stdin, /dev/fd/
164 and similar symlinks pre-created. This makes running shells
165 as container init process a lot more fun.
167 * The fstab support can now handle PARTUUID= and PARTLABEL=
170 * A new ConditionHost= condition has been added to match
171 against the hostname (with globs) and machine ID. This is
172 useful for clusters where a single OS image is used to
173 provision a large number of hosts which shall run slightly
174 different sets of services.
176 * Services which hit the restart limit will now be placed in a

185 * When running in --user mode systemd will now become a
186 subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps
187 tree a lot more organized.
189 * A new PartOf= unit dependency type has been introduced that
190 may be used to group services in a natural way.
192 * "systemctl enable" may now be used to enable instances of
195 * journalctl now prints error log levels in red, and
196 warning/notice log levels in bright white. It also supports
197 filtering by log level now.
199 * cgtop gained a new -n switch (similar to top), to configure
200 the maximum number of iterations to run for. It also gained
201 -b, to run in batch mode (accepting no input).
203 * The suffix ".service" may now be ommited on most systemctl
204 command lines involving service unit names.
206 * There's a new bus call in logind to lock all sessions, as
207 well as a loginctl verb for it "lock-sessions".
209 * libsystemd-logind.so gained a new call sd_journal_perror()
210 that works similar to libc perror() but logs to the journal
211 and encodes structured information about the error number.
213 * /etc/crypttab entries now understand the new keyfile-size=
216 * shutdown(8) now can send a (configurable) wall message when
217 a shutdown is cancelled.
219 * The mount propagation mode for the root file system will now
220 default to "shared", which is useful to make containers work
221 nicely out-of-the-box so that they receive new mounts from
222 the host. This can be undone locally by running "mount
223 --make-rprivate /" if needed.
225 * The prefdm.service file has been removed. Distributions
226 should maintain this unit downstream if they intend to keep
227 it around. However, we recommend writing normal unit files
228 for display managers instead.
230 * Since systemd is a crucial part of the OS we will now
231 default to a number of compiler switches that improve
232 security (hardening) such as read-only relocations, stack
233 protection, and suchlike.
235 * The TimeoutSec= setting for services is now split into
236 TimeoutStartSec= and TimeoutStopSec= to allow configuration
237 of individual time outs for the start and the stop phase of

249 * The journal and id128 C APIs are now fully documented as man
252 * Extra safety checks have been added when transitioning from
253 the initial RAM disk to the main system to avoid accidental
256 * /etc/crypttab entries now understand the new keyfile-offset=
259 * systemctl -t can now be used to filter by unit load state.
261 * The journal C API gained the new sd_journal_wait() call to
262 make writing synchronous journal clients easier.
264 * journalctl gained the new -D switch to show journals from a
267 * journalctl now displays a special marker between log
268 messages of two different boots.
270 * The journal is now explicitly flushed to /var via a service
271 systemd-journal-flush.service, rather than implicitly simply
272 by seeing /var/log/journal to be writable.
274 * journalctl (and the journal C APIs) can now match for much
275 more complex expressions, with alternatives and
278 * When transitioning from the initial RAM disk to the main
279 system we will now kill all processes in a killing spree to
280 ensure no processes stay around by accident.
282 * Three new specifiers may be used in unit files: %u, %h, %s
283 resolve to the user name, user home directory resp. user
284 shell. This is useful for running systemd user instances.
286 * We now automatically rotate journal files if their data
287 object hash table gets a fill level > 75%. We also size the
288 hash table based on the configured maximum file size. This
289 together should lower hash collisions drastically and thus
290 speed things up a bit.
292 * journalctl gained the new "--header" switch to introspect
293 header data of journal files.
295 * A new setting SystemCallFilters= has been added to services
296 which may be used to apply blacklists or whitelists to
297 system calls. This is based on SECCOMP Mode 2 of Linux 3.5.
299 * nspawn gained a new --link-journal= switch (and quicker: -j)
300 to link the container journal with the host. This makes it
301 very easy to centralize log viewing on the host for all
302 guests while still keeping the journal files separated.
304 * Many bugfixes and optimizations

313 * Several tools now understand kernel command line arguments,
314 which are only read when run in an initial RAM disk. They
315 usually follow closely their normal counterparts, but are
318 * There's a new tool to analyze the readahead files that are
319 automatically generated at boot. Use:
321 /usr/lib/systemd/systemd-readahead analyze /.readahead
323 * We now provide an early debug shell on tty9 if this enabled. Use:
325 systemctl enable debug-shell.service
327 * All plymouth related units have been moved into the Plymouth
328 package. Please make sure to upgrade your Plymouth version
331 * systemd-tmpfiles now supports getting passed the basename of
332 a configuration file only, in which case it will look for it
333 in all appropriate directories automatically.
335 * udevadm info now takes a /dev or /sys path as argument, and
336 does the right thing. Example:
338 udevadm info /dev/sda
339 udevadm info /sys/class/block/sda
341 * systemctl now prints a warning if a unit is stopped but a
342 unit that might trigger it continues to run. Example: a
343 service is stopped but the socket that activates it is left
346 * "systemctl status" will now mention if the log output was
347 shortened due to rotation since a service has been started.
349 * The journal API now exposes functions to determine the
350 "cutoff" times due to rotation.
352 * journald now understands SIGUSR1 and SIGUSR2 for triggering
353 immediately flushing of runtime logs to /var if possible,
354 resp. for triggering immediate rotation of the journal
357 * It is now considered an error if a service is attempted to
358 be stopped that is not loaded.
360 * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames.
362 * systemd-analyze now supports Python 3
364 * tmpfiles now supports cleaning up directories via aging
365 where the first level dirs are always kept around but
366 directories beneath it automatically aged. This is enabled
367 by prefixing the age field with '~'.
369 * Seat objects now expose CanGraphical, CanTTY properties
370 which is required to deal with very fast bootups where the
371 display manager might be running before the graphics drivers
372 completed initialization.
374 * Seat objects now expose a State property.
376 * We now include RPM macros for service enabling/disabling
377 based on the preset logic. We recommend RPM based
378 distributions to make use of these macros if possible. This
379 makes it simpler to reuse RPM spec files across
382 * We now make sure that the collected systemd unit name is
383 always valid when services log to the journal via
386 * There's a new man page kernel-command-line(7) detailing all
387 command line options we understand.
389 * The fstab generator may now be disabled at boot by passing
390 fstab=0 on the kernel command line.
392 * A new kernel command line option modules-load= is now understood
393 to load a specific kernel module statically, early at boot.
395 * Unit names specified on the systemctl command line are now
396 automatically escaped as needed. Also, if file system or
397 device paths are specified they are automatically turned
398 into the appropriate mount or device unit names. Example:
400 systemctl status /home
401 systemctl status /dev/sda
403 * The SysVConsole= configuration option has been removed from
406 * The SysV search path is no longer exported on the D-Bus
409 * The Names= option is been removed from unit file parsing.
411 * There's a new man page bootup(7) detailing the boot process.
413 * Every unit and every generator we ship with systemd now
414 comes with full documentation. The self-explanatory boot is
417 * A couple of services gained "systemd-" prefixes in their
418 name if they wrap systemd code, rather than only external
419 code. Among them fsck@.service which is now
420 systemd-fsck@.service.
422 * The HaveWatchdog property has been removed from the D-Bus
425 * systemd.confirm_spawn= on the kernel command line should now
428 * There's a new man page crypttab(5) which details all options
429 we actually understand.
431 * systemd-nspawn gained a new --capability= switch to pass
432 additional capabilities to the container.
434 * timedated will now read known NTP implementation unit names
435 from /usr/lib/systemd/ntp-units.d/*.list,
436 systemd-timedated-ntp.target has been removed.
438 * journalctl gained a new switch "-b" that lists log data of
439 the current boot only.
441 * The notify socket is in the abstract namespace again, in
442 order to support daemons which chroot() at start-up.
444 * There is a new Storage= configuration option for journald
445 which allows configuration of where log data should go. This
446 also provides a way to disable journal logging entirely, so
447 that data collected is only forwarded to the console, the
448 kernel log buffer or another syslog implementation.

458 * "systemctl help <unit>" now shows the man page if one is
461 * Several new man pages have been added.
463 * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=,
464 MaxLevelConsole= can now be specified in
465 journald.conf. These options allow reducing the amount of
466 data stored on disk or forwarded by the log level.
468 * TimerSlackNSec= can now be specified in system.conf for
469 PID1. This allows system-wide power savings.

480 /usr/bin/avahi-daemon" to get all log output of a specific

492 * Note that we skipped 139 releases here in order to set the
493 new version to something that is greater than both udev's
494 and systemd's most recent version number.
496 * udev: all udev sources are merged into the systemd source tree now.
497 All future udev development will happen in the systemd tree. It
498 is still fully supported to use the udev daemon and tools without
499 systemd running, like in initramfs or other init systems. Building
500 udev though, will require the *build* of the systemd tree, but
501 udev can be properly *run* without systemd.
503 * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles
504 should be used to create dead device nodes as workarounds for broken
507 * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is
508 no longer supported. udev_monitor_new_from_netlink() needs to be
509 used to subscribe to events.
511 * udev: when udevd is started by systemd, processes which are left
512 behind by forking them off of udev rules, are unconditionally cleaned
513 up and killed now after the event handling has finished. Services or
514 daemons must be started as systemd services. Services can be
515 pulled-in by udev to get started, but they can no longer be directly
516 forked by udev rules.
518 * udev: the daemon binary is called systemd-udevd now and installed
519 in /usr/lib/systemd/. Standalone builds or non-systemd systems need
520 to adapt to that, create symlink, or rename the binary after building
523 * libudev no longer provides these symbols:
524 udev_monitor_from_socket()
525 udev_queue_get_failed_list_entry()
526 udev_get_{dev,sys,run}_path()
527 The versions number was bumped and symbol versioning introduced.
529 * systemd-loginctl and systemd-journalctl have been renamed
530 to loginctl and journalctl to match systemctl.
532 * The config files: /etc/systemd/systemd-logind.conf and
533 /etc/systemd/systemd-journald.conf have been renamed to
534 logind.conf and journald.conf. Package updates should rename
535 the files to the new names on upgrade.
537 * For almost all files the license is now LGPL2.1+, changed
538 from the previous GPL2.0+. Exceptions are some minor stuff
539 of udev (which will be changed to LGPL2.1 eventually, too),
540 and the MIT licensed sd-daemon.[ch] library that is suitable
541 to be used as drop-in files.
543 * systemd and logind now handle system sleep states, in
544 particular suspending and hibernating.
546 * logind now implements a sleep/shutdown/idle inhibiting logic
547 suitable for a variety of uses. Soonishly Lennart will blog
548 about this in more detail.
550 * var-run.mount and var-lock.mount are no longer provided
551 (which prevously bind mounted these directories to their new
552 places). Distributions which have not converted these
553 directories to symlinks should consider stealing these files
554 from git history and add them downstream.
556 * We introduced the Documentation= field for units and added
557 this to all our shipped units. This is useful to make it
558 easier to explore the boot and the purpose of the various
561 * All smaller setup units (such as
562 systemd-vconsole-setup.service) now detect properly if they
563 are run in a container and are skipped when
564 appropriate. This guarantees an entirely noise-free boot in
565 Linux container environments such as systemd-nspawn.
567 * A framework for implementing offline system updates is now
568 integrated, for details see:
569 http://freedesktop.org/wiki/Software/systemd/SystemUpdates
571 * A new service type Type=idle is available now which helps us
572 avoiding ugly interleaving of getty output and boot status
575 * There's now a system-wide CapabilityBoundingSet= option to
576 globally reduce the set of capabilities for the
577 system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO,
578 CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or
579 even CAP_NET_ADMIN system-wide for secure systems.
581 * There are now system-wide DefaultLimitXXX= options to
582 globally change the defaults of the various resource limits
583 for all units started by PID 1.
585 * Harald Hoyer's systemd test suite has been integrated into
586 systemd which allows easy testing of systemd builds in qemu
587 and nspawn. (This is really awesome! Ask us for details!)
589 * The fstab parser is now implemented as generator, not inside
592 * systemctl will now warn you if .mount units generated from
593 /etc/fstab are out of date due to changes in fstab that
594 haven't been read by systemd yet.
596 * systemd is now suitable for usage in initrds. Dracut has
597 already been updated to make use of this. With this in place
598 initrds get a slight bit faster but primarily are much
599 easier to introspect and debug since "systemctl status" in
600 the host system can be used to introspect initrd services,
601 and the journal from the initrd is kept around too.
603 * systemd-delta has been added, a tool to explore differences
604 between user/admin configuration and vendor defaults.
606 * PrivateTmp= now affects both /tmp and /var/tmp.
608 * Boot time status messages are now much prettier and feature
609 proper english language. Booting up systemd has never been
612 * Read-ahead pack files now include the inode number of all
613 files to pre-cache. When the inode changes the pre-caching
614 is not attempted. This should be nicer to deal with updated
615 packages which might result in changes of read-ahead
618 * We now temporaritly lower the kernel's read_ahead_kb variable
619 when collecting read-ahead data to ensure the kernel's
620 built-in read-ahead does not add noise to our measurements
621 of necessary blocks to pre-cache.
623 * There's now RequiresMountsFor= to add automatic dependencies
624 for all mounts necessary for a specific file system path.
626 * MountAuto= and SwapAuto= have been removed from
627 system.conf. Mounting file systems at boot has to take place
630 * nspawn now learned a new switch --uuid= to set the machine
631 ID on the command line.
633 * nspawn now learned the -b switch to automatically search
636 * vt102 is now the default TERM for serial TTYs, upgraded from
639 * systemd-logind now works on VT-less systems.
641 * The build tree has been reorganized. The individual
642 components now have directories of their own.
644 * A new condition type ConditionPathIsReadWrite= is now available.
646 * nspawn learned the new -C switch to create cgroups for the
647 container in other hierarchies.
649 * We now have support for hardware watchdogs, configurable in
652 * The scheduled shutdown logic now has a public API.
654 * We now mount /tmp as tmpfs by default, but this can be
655 masked and /etc/fstab can override it.
657 * Since udisks doesn't make use of /media anymore we are not
658 mounting a tmpfs on it anymore.
660 * journalctl gained a new --local switch to only interleave
661 locally generated journal files.
663 * We can now load the IMA policy at boot automatically.
665 * The GTK tools have been split off into a systemd-ui.

681 * Support optional initialization of the machine ID from the
682 KVM or container configured UUID.
684 * Support immediate reboots with "systemctl reboot -ff"
686 * Show /etc/os-release data in systemd-analyze output
688 * Many bugfixes for the journal, including endianess fixes and
689 ensuring that disk space enforcement works
691 * sd-login.h is C++ comptaible again
693 * Extend the /etc/os-release format on request of the Debian
696 * We now refuse non-UTF8 strings used in various configuration
697 and unit files. This is done to ensure we don't pass invalid
698 data over D-Bus or expose it elsewhere.
700 * Register Mimo USB Screens as suitable for automatic seat
703 * Read SELinux client context from journal clients in a race
706 * Reorder configuration file lookup order. /etc now always
707 overrides /run in order to allow the administrator to always
708 and unconditionally override vendor supplied or
709 automatically generated data.
711 * The various user visible bits of the journal now have man
712 pages. We still lack man pages for the journal API calls
715 * We now ship all man pages in HTML format again in the

724 * This is mostly a bugfix release
726 * systems lacking /etc/os-release are no longer supported.
728 * Various functionality updates to libsystemd-login.so
730 * Track class of PAM logins to distuingish greeters from

737 * This is an important bugfix release for v41.
739 * Building man pages is now optional which should be useful
740 for those building systemd from git but unwilling to install
743 * Watchdog support for supervising services is now usable. In
744 a future release support for hardware watchdogs
745 (i.e. /dev/watchdog) will be added building on this.
747 * Service start rate limiting is now configurable and can be
748 turned off per service. When a start rate limit is hit a
749 reboot can automatically be triggered.
751 * New CanReboot(), CanPowerOff() bus calls in systemd-logind.

758 * The systemd binary is installed /usr/lib/systemd/systemd now;
759 An existing /sbin/init symlink needs to be adapted with the
762 * The code that loads kernel modules has been ported to invoke
763 libkmod directly, instead of modprobe. This means we do not
764 support systems with module-init-tools anymore.
766 * Watchdog support is now already useful, but still not
769 * A new kernel command line option systemd.setenv= is
770 understood to set system wide environment variables
773 * We now limit the set of capabilities of systemd-journald.
775 * We now set SIGPIPE to ignore by default, since it only is
776 useful in shell pipelines, and has little use in general
777 code. This can be disabled with IgnoreSIPIPE=no in unit

785 * This is mostly a bugfix release
787 * We now expose the reason why a service failed in the
788 "Result" D-Bus property.
790 * Rudimentary service watchdog support (will be completed over
791 the next few releases.)
793 * When systemd forks off in order execute some service we will
794 now immediately changes its argv[0] to reflect which process
795 it will execute. This is useful to minimize the time window
796 with a generic argv[0], which makes bootcharts more useful

803 * This is mostly a test release, but incorporates many
806 * New systemd-cgtop tool to show control groups by their
809 * Linking against libacl for ACLs is optional again. If
810 disabled, support tracking device access for active logins
811 goes becomes unavailable, and so does access to the user
812 journals by the respective users.
814 * If a group "adm" exists, journal files are automatically
815 owned by them, thus allow members of this group full access
816 to the system journal as well as all user journals.
818 * The journal now stores the SELinux context of the logging
819 client for all entries.
821 * Add C++ inclusion guards to all public headers
823 * New output mode "cat" in the journal to print only text
824 messages, without any meta data like date or time.
826 * Include tiny X server wrapper as a temporary stop-gap to
827 teach XOrg udev display enumeration. This is used by display
828 managers such as gdm, and will go away as soon as XOrg
829 learned native udev hotplugging for display devices.
831 * Add new systemd-cat tool for executing arbitrary programs
832 with STDERR/STDOUT connected to the journal. Can also act as
833 BSD logger replacement, and does so by default.
835 * Optionally store all locally generated coredumps in the
836 journal along with meta data.
838 * systemd-tmpfiles learnt four new commands: n, L, c, b, for
839 writing short strings to files (for usage for /sys), and for
840 creating symlinks, character and block device nodes.
842 * New unit file option ControlGroupPersistent= to make cgroups
843 persistent, following the mechanisms outlined in
844 http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
846 * Support multiple local RTCs in a sane way
848 * No longer monopolize IO when replaying readahead data on
849 rotating disks, since we might starve non-file-system IO to
850 death, since fanotify() will not see accesses done by blkid,
853 * Don't show kernel threads in systemd-cgls anymore, unless
854 requested with new -k switch.

860 * This is mostly a test release, but incorporates many
863 * The git repository moved to:
864 git://anongit.freedesktop.org/systemd/systemd
865 ssh://git.freedesktop.org/git/systemd/systemd
867 * First release with the journal
868 http://0pointer.de/blog/projects/the-journal.html
870 * The journal replaces both systemd-kmsg-syslogd and
871 systemd-stdout-bridge.
873 * New sd_pid_get_unit() API call in libsystemd-logind
875 * Many systemadm clean-ups
877 * Introduce remote-fs-pre.target which is ordered before all
878 remote mounts and may be used to start services before all
881 * Added Mageia support
883 * Add bash completion for systemd-loginctl
885 * Actively monitor PID file creation for daemons which exit in
886 the parent process before having finished writing the PID
887 file in the daemon process. Daemons which do this need to be
888 fixed (i.e. PID file creation must have finished before the
889 parent exits), but we now react a bit more gracefully to them.
891 * Add colourful boot output, mimicking the well-known output
892 of existing distributions.
894 * New option PassCredentials= for socket units, for
895 compatibility with a recent kernel ABI breakage.
897 * /etc/rc.local is now hooked in via a generator binary, and
898 thus will no longer act as synchronization point during
901 * systemctl list-unit-files now supports --root=.
903 * systemd-tmpfiles now understands two new commands: z, Z for
904 relabelling files according to the SELinux database. This is
905 useful to apply SELinux labels to specific files in /sys,
908 * Output of SysV services is now forwarded to both the console
909 and the journal by default, not only just the console.
911 * New man pages for all APIs from libsystemd-login.
913 * The build tree got reorganized and a the build system is a
914 lot more modular allowing embedded setups to specifically
915 select the components of systemd they are interested in.
917 * Support for Linux systems lacking the kernel VT subsystem is
920 * configure's --with-rootdir= got renamed to
921 --with-rootprefix= to follow the naming used by udev and
924 * Unless specified otherwise we'll now install to /usr instead
925 of /usr/local by default.
927 * Processes with '@' in argv[0][0] are now excluded from the
928 final shut-down killing spree, following the logic explained
930 http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
932 * All processes remaining in a service cgroup when we enter
933 the START or START_PRE states are now killed with
934 SIGKILL. That means it is no longer possible to spawn
935 background processes from ExecStart= lines (which was never
936 supported anyway, and bad style).
938 * New PropagateReloadTo=/PropagateReloadFrom= options to bind
939 reloading of units together.
